Data from a recent study suggest that a number of factors are involved in the development of Shift-work sleep disorder, and that environmental, genetic, familial and psychosocial factors all play a role in the development of this sleep disorder in shift-working women.
shift-work sleep disorder has a prevalence of 4% in a sample of U.S. nurses. This disorder may cause substantial harm to health and personal well-being. Recommendations regarding the need to control nesiritide exposure and sleep disturbance while working rotating shifts, especially during night shifts, should be investigated.
Bright morning light might decrease wakefulness, especially during the first hour of work. Bright morning light was safe in our healthy group of normovigilant workers. Bright-light exposure during daylight saving time (between 20-22:00) should be a safe option to reduce sleepiness in the workplace.
SHFSD is frequently present in the general population and affects more males than females. The prevalence of insomnia, and insomnia symptoms, are also high among the population. Males are more more frequently reported to complain of SHFSD than females. Sleepiness is a frequent complaint. Shift-work sleep disorder is closely related to a variety of sleep, psychopathology and health-related disorders such as depression, anxiety and alcohol or benzodiazepine use (hypnotics). Therefore, SHFSD should be included in sleep screening procedures.
In a recent study, findings does indicate that the present state of the science concerning shift-work sleep disorder has the potential to alter current knowledge about sleep and the functioning of circadian systems, which may affect future interventions.
The most common treatment for NMS is behavioral intervention (CBT and motivational interventions in combination), often in combination with medications. NMS may be effectively treated in order to restore sleep efficiency and sleep quantity.
SHSWD is more prevalent in the working population than what is found in the general population. A history of shiftwork is associated with SHSWD, emphasizing the importance of sleep hygiene for the prevention of sleep disruption at night.
The majority of studies have been published during or after 1997. Nevertheless, more than half of the literature reviewed dealt with the association between shift work and sleep problems. In spite of this, shift work sleep disorder remains a relatively unexplored topic.
Shifts are associated with an increased risk of shift-work sleep disorder. Shift workers may have worse sleep outcomes than day workers even if they meet all sleep and circadian requirements. The contribution of sleep fragmentation and circadian rhythm to shift-work sleep disorder warrants further research.
The shift work disorder is common in young adults and has significant impact on quality of life, especially for women. Moreover, this study provides clues for the design of clinical trials on sleep disturbances associated with shift work disorder.
As of February 2004, the number of clinical trials that investigated morning bright light for treatment of Shift-work sleep disorder is limited; however, a number of these tests demonstrate positive results involving this treatment. As clinical trials continue, it is hoped that additional evidence may lead to the recommendation of bright morning light therapy as a standard treatment.
In addition to light exposure alone, morning bright light therapy is typically used in combination with another photic intervention. Further research is required to identify the optimal timing of morning bright light therapy.
